Synthetic Transmission and Differential Fluids
Synthetic Transmission and Differential Fluids
(OP)
Manufacturers of synthetic fluids all claim that friction is reduced to the degree that drivetrain losses are reduced, and a power increase can be realized at the wheels.
Is this simply marketing BS? Have any of the auto manufacturers done testing to validate this?

industry(API) and private manufacturers. There is no
question that certain synthetic oils reduce internal
friction and extend service life. The real question is,
how much, for how long, under what conditions, and, are
synthetic oils cost effective? (marketing hype tends to
leave that data out)
Every dyno test I've seen shows the improvements to be
somewhere between non existant to about 2% improvement
depending on the product tested, it's application, the
vehicle, testing conditions, etc., etc., etc. The same
oil in a different vehicle under different conditions
could test out showing no benefit whatsoever. Go figure!
You gotta do your own homework and generalazitions are
worth about what you pay for them!!!!
Hope this helps!

If the OEM would have flown right in the first place, and stood behind his product, all of this would have been avoided

RE: Synthetic Transmission and Differential Fluids
We have to test the emissions and the fuel consumption of the car to sell it. One way of reducing those numbers is to fit synthetic oil. Another way might be to do something else, say aluminium suspension arms. Somebody makes a $/ mpg reduction decision, and you get synthetics or the suspension arms, or neither, or both. We do whichever is most profitable (we hope).
There's also the warranty thing. If we fit oil that is not deemed acceptable by the diff manufacturer then he won't pay his warranty. Synthetics have a higher temperature rating than conventional diff oil, so in some applications they are necessary.
